CHARLES DIEHL, OF NEW YORK, N. Y.

APPARATUS FOR LAYING OUT AND MARKING BOUND-TOP AWNINGS.

Specification of Letters Patent.

I Patented Dec. 10, 1907.

Application filed March 23. 1907. Serial No. 364.157-

To all whom it may concern: Be it known that I, CHARLES DIEHL, a citizen of the United States, and resident of the borough of Brooklyn, in the city and State of New York, have invented a new and -useful Apparatus for Laying Out and Marking Round-Top Awnings, of which the following is a specification.

The 'urpose of my invention is to overcome t e difficulty and complication which occur in laying out and cutting awnings to fit round-top windows.

My invention relates to an apparatus by which the cloth can be scored or marked so that when out on such marked or scored lines it will accurately fit a round top window of any'height and width. To this end I employ a horizontal table with a scale on which various widths of window may be indicated, and a vertical board used in conjunction with said horizontal table correspondingly scaled to indicate the width of the required awning and also scaled vertically to indicate the height thereof and in conjunction with these horizontal and vertical scale-boards I endploy clamps to hold the margin of the awning-cloth; the clamp bars which hold top and bottom edges of the cloth being in the form of circular arcs of 90 and of greater or less radius to correspond in form and dimensions with one-half the semi-circular top of a window of greater or less width.

In practice the awning is usually cut in half Width, that is to say, the width of cloth forms one-half the width of the awning, two similar pieces being cut with a quarter circle curve at top and bottom and united by a longitudinal seam to form the complete pattern with semicircular ends. Means are also provided for ready measurement of gores required to fill the spaces between the lower edge of the awning and the wall, on each side.

The invention relates also to other details hereinafter described and claimed.

In the accompanying drawings, Figure 1 is a perspective view of the apparatus, with cloth for a half awning stretched thereon in readiness for marking. Fig. 2 is a perspective view of the main portion of the apparatus without the cloth. Fig. 3 is a detail side view of an extensible clamp. Fig. 4 is an end view of the same. Fig. 5 is a detail vertical section.

The vertical board a is laid OH with a vertical scale I) for measuring the required height of the awning and with a horizontal scale 0 on which to measure one-half of its transverse width. A table (1 is attached to the vertical board a by hinges e permitting it to be folded up out of the way when not in use. On the outer edge of the table (1 folding legs f are mounted by hinges g so that said legs can be folded compactly against the bottom of the table, but serve when in use to support the table in horizontal position.

The table (1 is marked with a transverse scale it, corresponding with the scale 0 on the vertical board a, for measuring the halfwidth of the awning.

It is found convenient to lay off the scales 1) and 0 directly on the wall of the room or shop in which the awnings are to be cut and made up. The vertical board a may thus be regarded as a wall of such workroom or shop; but if preferred the vertical board a and horizontal table cl hinged thereto n ay constitute a detached and portable apparatus.

The cloth from which the half awning pattern is to be cut, is shown at A. For fastens ing and marking or scoring the upper and lower edges of the cloth I employ. a system of clamps made up of a vertical top bar j and a horizontal bottom bar 7c, each curved on a circular arc of 90 and of such radius that the length of such arcs will equal the half width of the required awning, corresponding with the width of the window to which it is to be fitted. A number of such curved clampbars j and 7c are thus employed, corresponding in length with the half width of the various widths of semi-circular top Windows. The face of the several clamp-bars is covered with thick felt, as shown at 7", k, to afiord the necessary friction for holding the cloth securely when stretched beneath such clamp bars for marking.

The parallel ends of the clamp bars 3' and 7c are formed with rabbets to fit in notches in clamp plates l, m, respectively pressed down by suitable springs n to hold such projecting ends of the clamp bars firmly down on the face of the board a and table (1. On the lower extremity of the curve of the upper clamp 'bar j is a projecting tongue 0 fitting in a socket in the upper end of a vertical extension bar p 1) made in two parts sliding one on the other within guide-loops q and held in any position of adjustment by a fixing screw 1' so that said vertical extension bar p may be made of any length to rest on the table 61 and support the curved clampbar 1' at the required height. The extremity so as to connect the vertical and horizontal clamping members. The bottom of the vertical extension bar p carries a projecting lug.

'0 (Figs. 3 and 5) which is engaged behind a horizontal clamp-bar w, which is hinged by its lower edge and pressed strongly against the face of the vertical board a by suitable springs to and retracted'by means of a pro j ecting lug or handle w The upper curved clamp bar and the extension bar p p are clamped firmly down on the cloth against the vertical board a by slotted bars 15 and clamp-screws t and the lower curved clamp-bar k and extension bar 8 s are firmly pressed down on the lower edge of the cloth on the table cl by similar slotted bars t and clamp screws t the cloth being tightly stretched while the clamps are tightened. This done the interior of the curves of the said clamp-bars j and 7c will be seen to form accurate guides on which the top and bottom edges of the half awning pattern can be marked or scored. The guide-clamps being in exact circular arcs and the cloth being stretched in exactly the position it will'ocupy in the awning, it will be apparent that the awning-pattern is marked out accurately and with the greatest possible facility. The vertical and horizontal clamp-bars p and s are shod or faced with felt, k, as already described with reference to the curved clamp bars.

I/Vith proper economy in cutting the cloth the width will necessarily leave an unfilled triangular space at a" (Fig. 1) in the extreme angle between the vertical board a and table d, requiring the insertion of a gore. In order to determine instantly and exactly the dimensions of this gore I employ a simple rectangular measuring bar 00, sealed in inches on both its horizontal and vertical arms, so that by setting this in the angle the horizontal and vertical dimensions of the space and of the required gore, can be at once-determined.

Any desirable number of the slotted pressure bars 23 and t may be employed to press the clamp bars j, is, p, s, tightly on the cloth, screw-socket-plates 25 being fixed to the face of the board a and the table (1 at short intervals for reception of the clamp screws t, t by which the pressure bars t, t are forced down. I have shown only a few of these screw socket plates for the purpose of illustration. Such screw socket plates are preferably countersunk or let in flush with the surface of the board and table, and a number of such countersunk screw socket plates 25 are provided some distance to the left of the first set, as illustrated. in Fig. 2, for use with narrower awning patterns.

While I have described the use of my ap paratus, for scoring or marking out awning patterns preparatory to cutting it will be apparent that the cloth may be directly out out with a knife while clamped as described, the several clamps serving as guides in cutting.

Having thus described my invention, the following is what I claim as new therein and desire to secure by Letters Patent.

1. In an apparatus for laying out and shaping round top awnings, the combination of a vertical board, a horizontal board, clamp-bars curved to correspoml with the ends of the desired awning pattern and adapted to form guides in marking the ends thereof, and means for fixing the said clampbars to the vertical and horizontal boards.

2. In an apparatus for laying out and marking round top awnings the combination of a vertical and a horizontal board, means for fixing them in position at a suitable angle to each other, clamp bars curved to correspond with the required shape of the ends of a round top awning, means for elamp ing said bars on said boards and clipping the ends of the awning in position for marking or scoring the same pre )aratory to cutting, and vertical and horizontal clan'ips connected to said curved clamp bars in position to clip the side of the awning pattern and form a guide for marking or scoring the same preparatory to cutting, substantially as described.

3. In an apparatus for laying out and. marking awning patterns the combination of pattern clamp bars adapted to clip the top and bottom edges of the cloth and form guides for marking the same, extensible clamp connections between said bars, serving to hold them in proper relative position at approximately right angles to each other, and means for pressing said top and bottom and connecting clamp bars against vertical and horizontal supports for marking or scoring the cloth, substantially as described.

4. In an apparatus for laying out and marking awning patterns the combination of curved clamp bars suitable to serve as markingguides for the top and bottom of awning patterns for round top windows, means for pressing said top and bottom clamping guides against the respective ends of the awning pattern on vertical and. horizontal supports, a vertical extension clamp-bar extending down from the curved clamp bar to the level of the horizontal support, means for pressing back the heel of said vertical extension clamp bar against the vertical support, a horizontal extension clamp bar extending back from the near end of the bottom curved clamp bar to the heel of the vertical extension clamp bar and means for conneetin g the meeting ends of said vertical and horizontal extension clamp bars, whereby the top and bottom curved clamps may be secured at proper juxtaposition at variable distance asunder for marking out awning patterns of different sizes.

5. In an apparatus for laying out and marking awning patterns for round top Windows the combination of vertical supports and horizontal supports on which the re spective ends of the cloth or pattern may be stretched for fitting and marking, quarter circle clamps for the top and bottom of the pattern adapted to serve as marking guides for one half the top and bottom of the awning pattern, clips for pressing the free ends of the quarter circle clamps against the vertical and horizontal supports at the longitudinal center of the awning pattern, extensible vertical and horizontal clamp bars connecting the op posite ends of the quarter circle clamps at variable distance' asunder and means for pressing the said curved and vertical and horizontal clamping guide bars upon the cloth on the vertical and horizontal supports in position for marking or scoring the cloth, substantially as described.
